Is it a better trend to add more and more batteries to increase range or keep a target 250ish mile range and over time remove batteries as they improve in power density?

First off range should be based off of 70mph/110kph since that's what actually matters when people talk about range (how far away from home can I get on a full tank?).

And 250 miles just isn't far enough to fully mitigate range anxiety. I would say about 300-350+ miles is the sweet spot that higher end makers should target.
